Split tube furnaces

“LK” split tube furnace with FeCrAl resistance heater

The distinctive characteristic of this versatile furnace model is its working space that can be opened along the longitudinal axis. With a maximum temperature of 1150 °C, the split tube furnace is a good solution for applications with gas or vacuum tight quartz working tubes.
Numerous modifications such as different stand variants, multizone versions or gas-tight installations make this furnace a real all-rounder.

“LK” split tube furnace with SiC heating elements

The split tube furnace with SiC heating elements is particularly suited as heating unit for complex systems, e.g. as reactor heater or as heating unit for rotary tube furnaces. The furnace distinguishes itself by its variable design of the working space. In particular it meets customers’ needs when working temperatures up to 1500 °C are required, without additional purging of the heating elements with protective gas.
